FIELD: chemical industry; production of composite materials with the strengthening filler and the star-shaped polyamide as the thermoplastic die, the precursor of these materials and the products produced out of them.
SUBSTANCE: the invention is pertaining to the product being the precursor of the composite material including the thread and-or the fibers of the polymeric matrix made out of the thermoplastic polyamide and the strengthening thread and\or, the strengthening fibers, the part of which may be made out of the thermoplastic polyamide. At that the thermoplastic polyamide of the matrix and\or the strengthening threads or the fibers contains at least one star-shaped polyamide including the star-shaped macromolecular chains containing one or several nuclei and at least three polyamide branches or three polyamide segments linked with the nucleus. Using the thermal molding or mangling the product, may be during several stages they produce the composite material, the composite semi-product and the final composite product with high mechanical properties, which may be used in the field of aviation and sport.
EFFECT: the invention ensures production of the final composite product with high mechanical properties, which may be used in the field of aviation and sport.
